Adobe Eases Privacy Concerns

Tests on the latest version of Adobe System’s e-reader software reveals the company is now collecting less data following a privacy-related row last month, according to the Electronic Frontier Foundation.

Digital Editions version 4.0.1 appears to only collect data on e-books that have DRM (Digital Rights Management), wrote Cooper Quintin, a staff technologist with the EFF. DRM places restrictions on how content can be used with the intent of thwarting piracy.

Adobe was criticized in early October after it was discovered Digital Editions collected metadata about e-books on a device, even if the e-books did not have DRM. Those logs were also sent to Adobe in plain text.

Since that data was not encrypted, critics including the EFF contended it posed major privacy risks for users. For example, plain text content could be intercepted by an interloper from a user who is on the same public Wi-Fi network.

Adobe said on Oct. 23 it fixed the issues in 4.0.1, saying it would not collect data on e-books without DRM and encrypt data that is transmitted back to the company.

Quintin wrote the EFF’s latest test showed the “only time we saw data going back to an Adobe server was when an e-book with DRM was opened for the first time. This data is most likely being sent back for DRM verification purposes, and it is being sent over HTTPS.”

If an e-book has DRM, Adobe may record how long a person reads it or the percentage of the content that is read, which is used for “metered” pricing models.

Other technical metrics are also collected, such as the IP address of the device downloading a book, a unique ID assigned to the specific applications being used at the time and a unique ID for the device, according to Adobe.

Twitter Tightens Security

Twitter Inc said it has put in place a security technology that makes it harder to spy on its users and called on other Internet firms to do the same, as Web providers look to thwart spying by government intelligence agencies.

The online messaging service, which began scrambling communications in 2011 using traditional HTTPS encryption, said on Friday it has added an advanced layer of protection for HTTPS known as “forward secrecy.”

“A year and a half ago, Twitter was first served completely over HTTPS,” the company said in a blog posting. “Since then, it has become clearer and clearer how important that step was to protecting our users’ privacy.”

Twitter’s move is the latest response from U.S. Internet firms following disclosures by former spy agency contractor Edward Snowden about widespread, classified U.S. government surveillance programs.

Facebook Inc, Google Inc, Microsoft Corp and Yahoo Inc have publicly complained that the government does not let them disclose data collection efforts. Some have adopted new privacy technologies to better secure user data.

Forward secrecy prevents attackers from exploiting one potential weakness in HTTPS, which is that large quantities of data can be unscrambled if spies are able to steal a single private “key” that is then used to encrypt all the data, said Dan Kaminsky, a well-known Internet security expert.

The more advanced technique repeatedly creates individual keys as new communications sessions are opened, making it impossible to use a master key to decrypt them, Kaminsky said.

“It is a good thing to do,” he said. “I’m glad this is the direction the industry is taking.”
